摘要:
A two-way communication circuit is connected to one end of a cable performing half-duplex communication. The two-way communication circuit includes a controller register storing a control signal including switch indication information switching a transmission direction and a reception direction; a communication controller managing timing depending on the control signal stored in the controller register; and a transmission and reception circuit periodically switching the transmission direction and the reception direction according to an indication by the communication controller depending on the control signal.
